(E)-3-(9-Anthr-yl)-1-(4-fluoro-phen-yl)-2-(4-nitro-1H-imidazol-1-yl)prop-2-en-1-one

(2E)-1-(2-Hy-droxy-5-methyl-phen-yl)-3-(4-meth-oxy-phen-yl)prop-2-en-1-one

In the title compound, C₁₇H₁₆O₃, the dihedral angle between the aromatic rings is 4.59 (7)° and an intra­molecular O—H⋯O hydrogen bond generates an S(6) ring. In the crystal, adjacent mol­ecules are linked by C—H⋯O hydrogen bonds, leading to the formation of [001] supra­molecular chains. Weak C—H⋯π inter­actions consolidate the packing.

(2E)-3-(2-Anthracen-2-yl)-1-(2-hy-droxy-phen-yl)prop-2-en-1-one

The asymmetric unit of the title compound, C₂₃H₁₆O₂, contains two independent mol­ecules in which the dihedral angles between the anthracene ring system and the benzene ring are 73.0 (3) and 73.3 (3)°. In both independent mol­ecules, the hy­droxy group is involved in an intra­molecular O—H⋯O hydrogen bond. The crystal packing is stabilized by π–π inter­actions [centroid–centroid distances = 3.6518 (9), 3.7070 (9) and 3.7632 (9) Å] and weak inter­molecular C—H⋯O hydrogen bonds.
